Lattice Semiconductor’s Q3 FY 2025 results reflected accelerating demand in the communications and computing end markets, supported by a growing security and board management footprint, as well as the introduction of new PQC-ready devices. Management signaled stronger bookings for H1 FY 2026 and reiterated the normalization of the industrial and auto channels by year-end, underpinning a constructive outlook.

What is Covered in this Article:

• Lattice’s Q3 FY 2025 financial results
• AI data center and server “companion FPGA” momentum
• PQC-ready control FPGAs expand security attach
• Industrial/auto inventory normalization tracking to plan
• Guidance and Final Thoughts

The News: Lattice Semiconductor (NASDAQ: LSCC) reported Q3 FY 2025 revenue of $133.3 million, up 4.9% year over year (YoY), versus Wall Street consensus of $133.0 million. End-market revenue was: Communications & Computing $74.0 million (+21% YoY), Industrial & Automotive $50.3 million (-7% YoY), Consumer $9.0 million (-24% YoY). Non-GAAP operating income was $38.7 million (+14.7% YoY) with a non-GAAP operating margin of 29.0% (Q3 FY 2024: 26.6%). Non-GAAP net income was $38.2 million (+17.2% YoY) and non-GAAP diluted EPS was $0.28 (Q3 FY 2024: $0.24).

“Lattice’s addressable market is growing due to the size of the infrastructure capital expenditures growing fast. Our diversified position in the largest and fastest growing application, growing attach rates, increasing average selling prices from our new products, broadening the application footprint of our small- and mid-range FPGA portfolio, and finally, increasing AI usage,” said Ford Tamer, Chief Executive Officer. “Taken together, we believe these dynamic factors are expanding dollar content for Lattice per customer system.”

Lattice Semiconductor Q3 FY 2025 Delivers Record Comms & Compute Revenue

Analyst Take: Lattice’s quarter underscores a clear mix shift toward communications and computing, where companion FPGAs for servers and networking are benefiting from AI infrastructure buildouts. Management highlighted stronger bookings—its best in six quarters—and reiterated confidence in 2026, while concurrently normalizing industrial/auto channel inventory by year-end.

Data Center and Communications Momentum

Communications and computing revenue reached a record $74.0 million (+21% YoY), reflecting broad traction across NICs, switches, routers, and security appliances, as well as server platforms. Management pointed to server demand as the principal driver, noting that year-to-date server revenue is up roughly 85% compared to 2024, and communications are up approximately 63% year to date. Lattice is being designed in as a companion FPGA across CPU (x86/Arm), AI accelerators (NVIDIA, AMD, Intel, hyperscaler ASICs), networking (Broadcom, Marvell, Mellanox, Cisco), and board/rack management. This expanding design-in footprint increases attach rates and ASPs as next-gen platforms scale through FY 2026. Management expects communications and computing to grow to about 60% of revenue in FY 2026, further concentrating the mix into higher-velocity areas. The implication is sustained demand visibility and content expansion as AI infrastructure spend persists.

PQC-Ready Control FPGAs Expand Security Attach

Lattice launched the MachXO5-NX TDQ family, billed as the industry’s first secure control FPGAs with full CNSA 2.0-compliant post-quantum cryptography (PQC) support. The timing aligns with rising enterprise and hyperscaler requirements for PQC, root of trust, and lifecycle security, driving attach in board management, rack management, and platform security controllers. At the OCP Global Summit, Lattice cited increasing interest in its low-power data center solutions and accelerating momentum across hyperscalers, neo-cloud, enterprise, and OEM/ODM ecosystems. These capabilities extend beyond traditional control into security, telemetry, and resilience functions, lifting dollar content per system. As PQC transitions from pilot to requirement, we expect security attach to become a structural tailwind. In short, PQC readiness deepens Lattice’s value proposition across compute and communications platforms.

Industrial/Auto Normalization and Share Capture

Industrial and automotive revenue of $50.3 million decreased 7% YoY as Lattice continued to ship under actual demand to normalize channel inventory in FY 2025. Inventory metrics improved (DIO down to 193 days from 242 a year ago), and management reiterated normalization by year-end, positioning the segment for renewed growth in FY 2026. Regionally, China’s automotive sector remained a relative bright spot, while aerospace and defense showed broad-based strength. Design activity continues across robotics, medical, test and measurement, and broader factory automation use cases, with Lattice highlighting share gains and new use cases. As shipping returns to natural demand, higher attach and ASP from new devices should support recovery. The takeaway is that inventory normalization—rather than demand—has constrained near-term revenue, with a clearer runway into FY 2026.

Guidance and Final Thoughts

For Q4 FY 2025, Lattice guided revenue to $138 million–$148 million (midpoint aligns with typical seasonal strength and bookings momentum), non-GAAP gross margin to 69.5% ±1%, and non-GAAP opex to $54.5 million–$56.5 million, with a 3%–5% non-GAAP tax rate and non-GAAP EPS of $0.30–$0.34. Management cited the strongest bookings in at least six quarters and continued acceleration in communications and computing, with industrial/auto poised to shift to natural demand post-normalization. Investment continues in Nexus and Avant roadmaps to sustain leadership in small- and mid-range FPGAs, with FY 2026 characterized as the “year of Nexus” and FY 2027 the “year of Avant.” Security attach and PQC-ready control FPGAs should further expand content in data center platforms.
